在白化病Wistar大鼠上，观察了迷走神经肝分支向延髓的投射。肝迷走神经刺激引起的复合场电位分析表明，该神经分支主要投射在延髓左侧。电刺激孤束核的神经分支可识别孤束核的传入神经元。采用碰撞试验分离传入和传出神经。部分支配肝脏的传入神经元对门静脉输注等渗葡萄糖溶液、高渗盐水和水有反应。它们的反应模式几乎与肝传入神经的反应模式相似。
Medullary projection of the hepatic branch of vagus was examined electrophysiologically in albino Wistar rats. Analysis of compound field potentials elicited by the hepatic vagal stimulation revealed that this nerve branch projects dominantly in the left side of the medulla. Afferent neurons in the solitary tract nucleus were identified by the electrical stimulation of the nerve branch. A collision test was employed to separate the afferent from the efferent. Some afferent neurons which innervate the liver were responsive to the portal infusion of isotonic glucose solution, hypertonic saline and water. Their response patterns were almost similar to those of the hepatic afferent nerves.
